Saw this, probably already here..

 

Oh, yes, legendary performer. The fiercest of Oldsmobile small blocks can never get too much attention. Mid 14s bone stock (quicker than new 442s...), mid 13s with headers and slicks. And the one in the article you posted a pic of was further modded. That one was launched off the line at 5500 rpm and shifted at 6200 rpm. They saw a 13.0 at 106 mph with 2 aboard. While burning out through all of 1st gear. Test weight 3870 lbs, 0–60 in 5 seconds. Incredible car. Test was conducted in below freezing temps. Better traction, 0-60 in 4s and 1/4 in 12s...

For reference, the quickest non-sports car from the original muscle era with a reliable original road test was the 1969 ZL1 Camaro (427 big block), which saw a best of 13.1 @ 110mph. Bone stock.

Here is the complete write-up of the car you posted. https://over-drive-magazine.com/wp-c...C-W-31-1-6.pdf

And the one that was just headers and slicks. https://www.hemmings.com/stories/ram...tlass-ram-rod/

 

Cool story. Two guys in the car added 320 pounds ? Were they jockey”s lol.

Has anyone seen any of the literature that you could send away for at the time ?

 

I was there for a visit in1968. The special jets and metering rods could be ordered through any GM parts dealer at the time. They did chassis dyno tuning in a bay or two. They campaigned a 442 in NHRA and wouldn't show up anyplace that Berejik Olds would be. Their NHRA legal 442 couldn't run on the national record. They highly advertised their products in one certain magazine.
